At the end of Simpsons Episode #2710 tonight, which had a subplot of Lisa in the play "Casablanca", there was a Humphrey Bogart-like kid. The end of the episode showed cartoon stills of Treasure of the Sierra Madre, African Queen, and the arch scene from "Once Upon a Time in the West", complete with a Frank character leaning against the arch while the kid had his brother supported on his shoulders, the head in the noose.

I just can't figure out why that was in the episode, except an inside joke from a Leone worshipper like us. But very cool, rewound and watched that part again on DVR. No spaghetti western music though.
